摘要
建立了基质固相分散-气相色谱-氢火焰离子化检测器同时检测甘蔗中7种三嗪类除草剂(西玛津、莠去津、特丁津、西草净、阿灭净、扑草净、特丁净)残留量的方法。甘蔗样品经弗罗里硅土研磨均匀后,石墨化碳黑净化,无水硫酸钠脱水,乙腈淋洗,旋蒸浓缩后用气相色谱检测。7种除草剂在0.5～10.0μg/mL范围内具有良好的线性,相关系数在0.9964～0.9992之间;7种除草剂的检测限为0.01～0.04mg/Kg,样品的添加回收率为82.2%～93.4%,相对标准偏差为2.7%～7.2%。
A method based on matrix solid-phase dispersion (MSPD) and gas chromatography (with flame ionization detector) was developed to detect the residues of the seven kinds of triazine herbicides in sugarcane-simazine,atrazine,terbuthylazine,simetryne,ametrex,prometryne and terbutyrn hexazinone.Sugarcane samples were detected by gas chromatography after grinded evenly by florisil,purified by graphitized carbon black (GCB),dehydrated by anhydrous sodium sulfate,leached by acetonitrile and rotary steam condensed.Th...
